Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561856, here are decompositions:

5 + 33561851 = 33561856
17 + 33561839 = 33561856
89 + 33561767 = 33561856
113 + 33561743 = 33561856
137 + 33561719 = 33561856
257 + 33561599 = 33561856
353 + 33561503 = 33561856
443 + 33561413 = 33561856

Showing the first eight; more decompositions exist.
